Let's not forget the simplest end point to all the manufacturers.... MAKING MONEY.

The undertail exhaust use more material without a doubt, the whole underbelly has nothing to do with emmisions, but about mass centralization and whats TRENDY and costs the least amount of money to make...

While i enjoy performance i will really never need to eek out every ounce i can find, because im not the kind of guy to hit the track. The difference between undertail and low-slung exhausts will be nearly non existant to me at my level of riding, even in the mountains.

This bike is already outperforming my needs in every aspect. So i dont feel a real urge to argue over the drawbacks of exhaust placement.

How many of us REALLY ride this bike to its limit anyway?

Now i do like the fact that if i low side my bike, there is a very good chance the exhaust will come out fine because it is an undertail exhaust. I also like that fact i dont have burns on the inside of my calf/ankle like i did on my SV650s.

You don't need to be riding at the peak of performance to notice a difference. I took the underseat exhaust off my old FZ-6 and it was nearly 30 pounds shed off the bike. I noticed a huge difference in handling.

I think the underseat exhaust looks cool, but it is a pain in the ass when trying to pack and travel.

I'm thinking my Zard system dropped the weight by about 15 lbs and dropped it lower on the bike. Can't be a bad thing. Ducati's undertails were serious ass roasters. Who needs a headed seat when you have undertail exhaust!!

As someone who rides year-round in New York, I can say that I enjoy the undertail in the winter months!

The weight and placement is significant, though, even on the road. Please, let's not compare a street bike to a MotoGP bike. If they think the need the exhaust volume and running one pipe undertail gets them there, they can mitigate the negative effects with lots of unobtainium and money. They're not running steel exhausts designed to be cost effective while lasting many thousand road miles.

As far as offering an undertail as an option, it's possible but probably not practical. More parts to test, produce and stock and. Then you've got a mod which goes against the mass-centralization engineering and might actually lessen performance. Best left to the aftermarket.

I've heard an aftermarket undertail for the Panigale (was it a Zard ?) offers an advantage of about 20 hp in the midrange versus the OEM one, exactly what their pilots want, but they probably won't get it because they're tied to Termignoni and the lowboy dogma

I would love a low exhaust simply so my ass doesn't fry. Nothing worse than heading somewhere only to realize that your ass is soaked by the time you get there. This might only be a problem for those of us that are prone to swamp ass, I realize..
